This is basically what I used to brainstorm when working on my procedural bricks; experiments with shading, and various styles. A small number of these is what turned into my Shiny Noise Bricks. I tend to make something from scratch, then try and generalize it with code, see what comes out, refine, make more stuff manually, try to integrate it, and so on. It's a back and forth process.

Enjoy!
